exact description.

.My .invention relatesto a new and improvedradiator construction,` andthis case .is a diiision from mzy co-pending applicaftion, Serial No.493,544,"led May '3rd, 1909.

The main object of the invention relates to improved structural featureswhereby a radiator may be produced at a mlnimumof withoutsacrifice-tostrength or durability.

Afx'diator, as constructed,` will befound to beef particularntility whenemployed .in
